This is a guest post from Shaida Badiee and Eric Swanson, co-founders of the NGO Open Data Watch, which works on a variety of initiatives at the intersection of Open Data and Official Statistics.
Although "open data" has been a popular rallying cry and many countries, states, even cities, have announced open data initiatives, open access to the important data produced by national statistical agencies remains, at best, limited.
To get a baseline measurement, Open Data Watch conducted in depth assessments of the statistics commonly produced by national statistical systems in 125 mostly low- and middle-income countries. Called the Open Data Inventory (ODIN), results are now available online at http://odin.opendatawatch.com. Global results are shown in Figure 1. In 2015 ODIN found only 10 national statistical offices (NSOs) that satisfied more than 50 percent of the criteria for data coverage and openness. Mexico, at 68 percent was the highest scoring country followed by Mongolia, Moldova, and Rwanda. Uzbekistan at 3 percent was the lowest.
An interactive table of all country scores is available here:
